In the official CS 1.6 BETA Forum, Valve developer Toni Sergi has posted that he has found a possible fix for the infamous flash bug that has plagued Counter Strike for years. The developer apparently was able to do a very quick fix for this problem. Valve has come under fire in recent days for its patch to fix "Russian Walking".

The "flashbug" caused the flash grenade to effect players in areas where it should not and has been the cause of many disputes in competitive CS over the years. The bug was so important to the competitive community that "flash bug fixed maps" were used by most leagues and professional organizations. No estimated time for when the fix will be implemented has been given.

Below is a snippet from the posts by Valve developer Toni Sergi.

"Okay, I just worked out a potential fix; it at the very least fixed THAT one, it _should_ fix all of them though."

"I read the thread, went for a smoke, had an idea for what's causing it from the youtube video tested it out unmodified to duplicate the bug (by making the flashbang not explode for 20 seconds so i could get into position), went 'hmmm..', made the change to attempt to fix it, went in and tested again, no flash in tunnel. but i can still be flashed under normal circumstance." -Toni Sergi
